The Eclipse ioFog set of technologies is a fog computing layer that can be installed on any hardware running Linux. Once installed, it provides a universal runtime for microservices to run on the edge. In addition to a common runtime, ioFog also provides a set of useful services including a message bus, dynamic configuration of the microservices, and remote debugging.
Automated interconnection of ioFog instances is provided by the ComSat component. This relieves developers from writing code just to move data from one place to another.
Orchestration and management of microservices (the edge software) is provided by the ioAuthoring application and the ioFog instances receive their instructions through the fabric controller.
Working together, these components provide a full set of technologies for building and running IoT software the executes wherever the developer chooses.
In greater detail, the fog computing layer is comprised of the following:
1. A fog computing software agent that runs on various operating systems and provides a universal runtime for IoT microservices. This is called "ioFog".
6. A local software development tool that mimics the fog computing runtime and gives developers a way to test their code against simulated situations before making the effort to package their code as a microservice. This is called "Test Message Generator".
